Prince George’s County is getting a do-over after a government oversight office ruled the headquarters selection process that kept a major federal agency in Montgomery County was flawed. The Government Accountability Office ruled that bids for the new Department of Health and Human Services headquarters weren’t evaluated by the same guidelines that had been outlined in the solicitation.

The ruling is a response to an appeal filed in April by three developers, including two in Prince George’s, protesting the General Services Administration’s decision to renew its lease and keep HHS’ more than 3,000 employees in Rockville.
